Our experiments showed no evidence of ~(210)Po half-life change at low temperature. A reduction of the half-life of ~(210)Po by 6.3percent at low temperature, as claimed by Raiola et al. (2007), would have lead to a decay-corrected activity reduction of about 1percent after 29 days,...

210Po and 210Pb are members of the natural 238U series and two of the relatively long-lasting radionuclides (210Po half life 138.4 day, 210Pb 22.3 year) of radon decay products. A report of the UNSCEAR (UNSCEAR, 1993) indicated that 210Po is estimated to be about 7% of the total ...

210Po has a half-life of 138.4 days and emits 5.3 MeV α-particles. Despite its short half-life, it remains in the atmosphere for a long time due to its long half-life parent radionuclides (210Pb,226Ra). Therefore, the amount of210Po in the environment is largely dependent on the...
Polonium210Po, a product of the uranium-radium decay chain, is an alpha emitter with a half-life of 138.38 days, with a specific activity of 166 TBq·g−1(Persson2014; Persson and Holm2011).210Po is known as one of the most carcinogenic radionuclides, and its radiotoxic properties gaine...
This isotope is separated from the short-lived daughters by Pb-210 (beta emitter with 22 years half life). The CR-39 detectors were placed on the surfaces of different filters for 3 months for two different post-sampling times. The counting results showed very good correlation with the ...
